Dear colleagues,

ensuring the supply of high-quality drinking water for future generations is a task that drives us at TZW for our customers and partners in water supply, authorities and science. This applies to normal operations as well as in times of very high water demand. The articles on persistent and mobile substances and on microplastics in the aquatic environment take up relevant topics and show which solutions need to be initiated. In the course of climate change, the focus is particularly on peak consumption periods in drinking water supply. A project on peak consumption and peak factors was recently completed at TZW. We present first results. A current DVGW project at TZW is investigating what the new microbiological parameters of the EU Drinking Water Directive mean for the German water sector.

Have an inspiring reading.

Persistent and mobile organic trace contaminants require continuously adapted methods

Spurenstoffe

Organic micropollutants with very high polarity are not only an analytical challenge. If they are also persistent, they pose a challenge for water supply, as they are not efficiently removed by biological or chemical degradation, nor by sorption in natural systems and during water treatment. TZW is continuously expanding the analytical possibilities for such PM substances, many of which are obviously ubiquitous.

Findings from 3.5 years of microplastic research in the Danube catchment area

Video MicBin Standbild

Since 2017, the joint research project MicBin has been investigating how plastics and, in particular, so-called microplastics get into rivers, what happens to them there and how they can be sampled and analysed. The project coordinator, Dr. Nicole Zumbülte, gave a detailed interview to the German Federal Ministry of Education and Research (BMBF) on the results and conclusions from MicBin. At the same time, an informative short video has been released, summarising the work of the scientists in 2 minutes.

Identify trends for peak consumption in water supply

Bild Bewässerung

The operation of water management facilities is subject to partly contradictory changes in boundary conditions. On the one hand, a decreasing per capita consumption has been observed in the past decades, but on the other hand, a climate-related increase in peak demand, especially in the summer months. TZW has investigated the development of peak consumption in a DVGW research project. In addition, teams of experts are developing digital tools for forecasting short-term water demand in order to be able to support daily operations under the challenge of an increasing gap between base and peak demand.

EU-DWD: What the new microbiological parameters mean for German water supply

In the new EU Drinking Water Directive (EU-DWD) adopted in January 2021, a so-called "risk-based approach" was included, which provides, among other things, that the raw water and, if necessary, also the treated water should be tested for "somatic coliphages" as an operational parameter. The way in which this requirement is implemented is under the responsibility of the member states. The aim of this DVGW research project is to conduct a microbial risk assessment through data evaluation and specific investigations for pathogens and indicators in various exemplary water works, covering the range of water treatment processes commonly used in Germany. This is meant to serve as a basis for a sensible and appropriate implementation of the microbiological requirements of the new EU Directive into national law.

News in brief from TZW

EU Green Week 2021_ ZERO POLLUTION

The EU Action Plan toward a Zero Pollution Ambition is a key action of the European Green Deal. EU Green Week 2021 will be an opportunity to engage with all stakeholders and interested citizens on how we can work together to make the ambition for a zero pollution and toxic-free environment a reality. Our CEO Dr Josef Klinger (TZW) and Prof. Francesco Fatone (UNIVPM, WWEELab), as Water Europe Vision Leader Team 'Value in Water', will discuss the opportunities and challenges of resource recovery from water on 28.05.2021.

New innovation challenge “Generate value from brines”

The EU project Water Test Network supports small and medium-sized companies (SMEs) to develop marketable products for the water sector. TZW is part of this network as a German test institute. Until 05/09/2021 a new innovation challenge is running, looking for SMEs with innovative technologies to generate value from brines. For more information click here.

 

Final report TRUST now available

Over a period of three and a half years, the BMBF joint project TRUST used the example of the Río Lurín catchment area in Peru to develop inter- and transdisciplinary concepts for drinking water use, safe wastewater disposal and water reuse. For TZW as project partner, the departments of water microbiology, risk management and technology concepts were involved. The final report is now online and presents the approaches and results developed in the TRUST project. Link to the report 

 

Dr Karsten Nödler wins poster prize of the Water Chemistry Society

At this year's annual meeting of the Water Chemistry Society, Dr Karsten Nödler from TZW’s Water Chemistry Department was awarded the prize for the best poster. His work on trifluoroacetate in beer beat out more than 80 other poster presentations. The results were also published in the journal “Food Chemistry” and thus presented to an international readership. We warmly congratulate Dr Nödler on this success.
